1 flow regulators Why use smartflow Flow Regulators? Create Repeatable and Balanced Processes Multiple circuits within an injection mold often have different cooling requirements. Cooling water will normally follow the path of least resistance leaving some circuits starved for water in manifolds without regulators. Individual circuit control allows the operator to direct the process cooling water where needed to produce repeatable finished part quality. Optimize Cooling Capacity By applying the principles of Turbulent Flow, cooling circuits can be optimized for efficient cooling, conserving water and electricity. Additional water flow rate beyond turbulent flow condition provides diminishing returns illustrated by the chart below. Steel Temperature, F Unstable Steel Temp Predicted Turbulent Flow Transition Stable & Efficient Wasted Pumping Capacity? Implement Scientific Cooling SM Flow Regulators help injection molders use the three R s of Scientific Cooling: Reveal, Record, Repeat. Burger & Brown Engineering recommends placing flow regulators on the return side of the cooling water loop. This position ensures that the cooling lines are full of cooling water. Regulators placed on the supply side may provide only a small stream of water to the cooling lines. The water may not come in contact with all internal cooling surfaces providing inconsistent part cooling. Using Smartflow Flow Regulators to apply the principles of Turbulent Flow and Scientific Cooling, injection molders optimize cooling water and energy efficiency while providing the best possible environment to make repeatable parts Cooling Flow Rate, GPM Try our On-Line Calculators for Injection molders accessible from the home page: For 3D CAD files of Custom Manifold Assemblies and Standard Components Visit Scientific Cooling Calculator extracts cooling water flow rate, heat transfer, processing temperatures, and overall cooling requirements based on polymer type, processing temperature, shot weight and other variables. Turbulent Flow Calculator flow rate needed to achieve turbulence based on the Reynolds Number, cooling water temperature and inside diameter of the cooling channel. 9

2 Brass flow regulators Smartflow flow regulators provide a unique, leak-free, single-point manual flow control. This regulator incorporates the proven mechanical flowmeter and integral needle valve in a compact design. Very few moving parts improve reliability and leak-free operation. Used singly or in combination with a water manifold, the flow regulator allows manual control of individual cooling water lines. Features and Benefits Compact size works well in restricted-space locations. Rugged construction provides years of dependable service. 210 F (99 C) Temperature Rating allows installation into a wide range of applications. Optional Temperature Gauge displays additional process information. No Mounting Restrictions ease installation in any position without extra brackets or hardware.
